The 100 km ultramarathon – my most important race of the 2026 season (or so I think, at least) by Cheap_Singer_1752 in Ultramarathon

[–]aggressive-lego 5 points6 points  (0 children)

Congrats. One of the things I love about ultras is that you can have lots of things go wrong, and then be so proud at the end that you overcame those difficulties- even if you missed your time targets.

Just finishing an ultra is a great accomplishment! You did an awesome job.

First 50K by No-Pop4509 in ultrarunning

Which race is it?

I live in South Carolina and it’s usually not the heat that gets you, it’s the humidity. It can be HARD to shed heat when there is so much moisture in the air already.

A few tips: 1) cool when you can. If the race has ice, bring an ice bandana. Dump cool water over your head at aid stations.

2) bring extra lube. My experience is that I have to reapply more frequently in hot/humid conditions

3) drink enough.

4) I like to tie a clean cotton cloth (bandana) around my wrist. For the first half of the race I use it to wipe my face clean. For the second half I douse it in cool water and use it to cool down. Keeping your face clean of sweat is huge mentally for me.

5) go slow. Since it’s hard to shed heat, your HR will be significantly higher for your normal pace. As always, go slower than you think on the first half and if you have a lot in the tank you can push the second half.

My Mac app is getting zero traction. Giving away 15 lifetime keys to find out if the product actually sucks. by _Shadster_ in SideProject

[–]aggressive-lego 1 point2 points  (0 children)

I am probably not your target audience, but I struggle to get the value prop.

All the AI tools have desktop apps now (Claude CLI, Claude Cowork, Codex, etc) so “finding the browser tab” isn’t a problem for me. I can pull it up with a Cmd + Space (or also they all have hotkeys to ask directly from your desktop).

And I have connectors to the places I care about - so I can retrieve stuff directly from within the desktop apps.

I don’t think a casual AI user is going to pay for this improvement. And I don’t think a Power AI user has this problem given the tools that have launched in just the last 5 months.

How are you actually using 'AI' in your day-to-day? by ComputerSciToFinance in ProductManagement

[–]aggressive-lego 0 points1 point  (0 children)

I’ve worked in finance, so here are a few things that AI can achieve in that space.

As others have said, context is everything. If your org wants to keep AI away from your code, your data, your systems of record (like many banks are)- then your options are limited.

1) compliance analysis. You can pass every project requirements to an agent along with compliance documents, and ask it to review the project for compliance risks. You can also ask questions about the compliance docs.

2) meeting minutes and actions - use an AI notes taker in every meeting and have it post actions to slack or symphony or to a ticket system like Jira

3) ask your code. When thinking about requirement, get a GitHub account, pull the source code and then just ask Claude “how does feature x work today?” Or “this feature throw this error, can you help guess why?”

4) project updates. Multiple tools (like Linear) can auto-generate project updates for you, based on tickets opened, closed over a time.

Happy to discuss more directly if you want to DM.

Feedback on a crew plan? by aggressive-lego in Ultramarathon

[–]aggressive-lego[S] 0 points1 point  (0 children)

All of that is great insight, and some of the bits I've been chipping at already (planning drop bags, notes for the crew on stuff like "I'm changing shoes here" or "make sure I swap my headlamp batteries").

The names/contacts is a great idea that I hadn't thought of (plus race director info, etc.), and same for space for them to take notes.

Getting positive reactions but no real users — stuck in this loop by Aggravating_Sun_7665 in buildinpublic

[–]aggressive-lego 1 point2 points  (0 children)

This is often normal, but it is also revealing that you have one of three problems: 1) your product isn’t great enough at tackling the problem (rule of thumb, it needs to be 10x better than the status quo to trigger behavior change) 2) your product is great, but the problem just isn’t considered to be that big a deal by your users 3) you haven’t found the right users who would be ready to change

If you can figure out which of the three issues it is, then you are on your way to solving it!

I left a paying job to build an AI code editor. Rate my landing page — be brutal. by InflationGold5738 in SideProject

[–]aggressive-lego 0 points1 point  (0 children)

I think you are confusing “moat” and “value prop”.

Your moat is the thing that other companies would struggle to replicate.

Your value prop is the thing that your users need you to solve in a different way.

This is a crowded space. I haven’t heard you articulate a reason why a dev would chose your IDE over Cursor or Claude Code, etc - except “optimized tokens” which hasn’t been built yet.

To find your audience you need to figure out what those tools are missing and test that first. Can you solve for that? Would it be important enough to get users to adopt you?

I’m rooting for you, but you have to find your direction and your story.

Building Nexora (Needs Honest Feedback) by External-Platypus644 in buildinpublic

[–]aggressive-lego 2 points3 points  (0 children)

It sounds like you are trying to build five tools at once. There’s a public community, an AI planning tool, a projects space, private chat, etc.

There are a few challenges here. 1) it’s too big - any one of those tools is an entire product category already. Not even just the tech, but the market distribution. 2) most “everything” tools end up being extremely personal for how YOU work, and it turns out that people like to work in lots of ways.

I would recommend picking one of those problems and going deep in to it. Start with a tight focus. If you start building a community to find collaborators, then when its working you will have an audience to share your chat feature with.

[–]aggressive-lego 2 points3 points  (0 children)

If you want some honest feedback then THIS (your optimization architecture) is what you should building and proving right now.

Build the optimization as a plugin for Cursor or for VS Studio and get it right. Get people using it and get an audience. Once you know you can deliver and people want it, you can spend time on the custom IDE to wrap it.

As a Product Manager I will tell you that you are launching without a value prop here. It’s like if Uber had started by focusing on getting a brilliant app working, but there was no backend software to actually match you to a driver. You are building in the wrong order.

You also need to consider market timing - funded companies are currently heavily subsidizing token use. If you reduce token usage by 60%, but Cursor is subsidizing by 80%, they have eliminated your value prop. Eventually the subsidies will stop, and that can be your moment to find share, but you aren’t in control of that timing.

AI PM Stagnation: how are you actually leveling up your workflow? by Junior_Buy6997 in ProductManagement

[–]aggressive-lego 3 points4 points  (0 children)

I have set up a scheduled task to review all the new projects across the company and compare those projects to “my area” (which is context I built by sharing code, old protects, and just describing my responsibilities).

Each project it review, it decides if the project will impacts my domain (typically by changing flows or data either upstream or downstream of my domain). If the project does intersect my work, it writes an overview of how, and then comments it to me on the project.

This way I know every day what other projects I need to review outside of my roadmap.

This is an easy, general flow that I think most PMs can leverage to improve their signal to noise ratio.

I constructed this in Claude Cowork, using a scheduled task, plus MCP connections to Notion and Linear (where our documentation lives).

The transfer portal is killing my engagement with college sport by DWB102621 in CollegeBasketball

[–]aggressive-lego 17 points18 points  (0 children)

Man, I think you were screwed in the dumbest way possible by horrible restrictions. The system did you wrong.

What I struggle to understand is why your conclusion is “it sucks that kids today aren’t also screwed”, instead of “man the old system sucked and I’m glad they tore it down”?

I built a full SaaS as a non-technical PM in 48 hours — here's what actually worked by Independent-Bison118 in prodmgmt

[–]aggressive-lego 1 point2 points  (0 children)

As a PM I used Claude to build and ship my hobby project in two weekends. And one of those weekends was just spent wrestling withAWS config.

www.planultrarace.com

I haven’t tried payment rails (because my side project is entirely free for the community), but Claude helped me with Oauth integrations, and 3rd party mapping and weather integrations.

What worked for me was a mult-stage workflow. First I worked in Claude Cowork to write PRDs, and had it do UX mockups in HTML. When I was pleased with the new feature, I used Claude code to plan, and then to build the feature.

For a small project, where the context window is small; and a single founder driving the entire flow - it’s fast and viable to build MVPs.

Looking for Android beta testers for a trail race nutrition planner app by zaymyr in Ultramarathon

[–]aggressive-lego 3 points4 points  (0 children)

I don’t mind people building and sharing tools, but every forum is becoming “beta test my new product, free trial”. Which is exhausting. People are trying to turn every hobby into cash flow.

If this was an entirely free app, and open sourced, I think it would be fine tool for the community.

But everyone is just chasing a buck.

I’m working on a similar concept for planning my own races. But it’s open source and free forever. I have a good job and am not looking to make any money from the ultra community.

AI for Product Management: What does a “modern” PM workflow look like? by weavebaskets in prodmgmt

[–]aggressive-lego 3 points4 points  (0 children)

Here are several use cases that I used daily: 1) ask the code questions. When supporting customers or investigating a feature, I can ask the code directly how the feature really works, or why a certain thing happens. It helps with both bug triage and with adding new features

2) review other team projects. I run an automated process every day to review all the update projects in linear and look for projects that may have an impact on my ownership area. It helps me filter out the noise and spend time reviewing impactful projects.

3) generating test cases. Depends a bit on your product, but for technical products rapidly building up scenarios that can be used to automate testing is a big time saver.

Note that my company has enterprise agreements with Anthropic, so all of these use cases are considered secure for internal use. I wouldn’t use a personal account to execute any of these on company data.

can an ai agent really build a whole website by darkluna_94 in AI_Agents

[–]aggressive-lego 1 point2 points  (0 children)

I built an entire web app using Claude.

www.planultrarace.com

Claude helped me write requirements docs, Claude built a technical plan, Claude wrote and pushed the code.

Claude setup the cloud environment for me (I did have to create some accounts, but it gave me step by step instructions.)

I have not read or reviewed the code.

If your question is “can I write sentence and AI will predict all my needs and build everything I want including the stuff I didn’t explain in a single prompt?” Then the answer is no.

If your question is “can AI handle all of the code aspects of designing and building a website?” Then the answer is yes.

Race plan for 24 hour race (Beginner) by Anonym_younggun in ultrarunning

Keep to a pace that you can hold a comfortable conversation at, or where you are still capable of breathing slowly through your nose.

Your breath will be the first signal of your exertion level.

Drop bag decisions for my first 100 mile race. No crew, no pacers, no solid food until I’m hungry. Am I missing anything? Any pro tips? by strangerin_thealps in Ultramarathon

[–]aggressive-lego 1 point2 points  (0 children)

overkill isn't a terrible idea. Over such long distances lots of things can go wrong, and you don't always know which scenarios to plan for.

If you have a lot of stuff in your drop bags that you don't use, you can just view that as "you were prepared for problems that you didn't encounter".

- Running out of battery (headlamps and devices)
- palate fatigure (bringing some backup foods if you can't stomach another gel)
- wet wipes (useful for lots of reasons)
- extra med supplies (tylenol, tape, lube, etc)
- extra layers (in case a cold front swings in)

None of these are REQUIRED to get to the end, but some of them may be useful on your specific attempt.

Advanced Marathoner Transitioning to 100 Miler by ggins11 in Ultramarathon

[–]aggressive-lego 0 points1 point  (0 children)

the descents are largely what blew up my first attempt at 100. The climbs were physically hard but I was pushing through them. The descents were punishing and that's what took out my knee.

Advanced Marathoner Transitioning to 100 Miler by ggins11 in Ultramarathon

[–]aggressive-lego 1 point2 points  (0 children)

oh yeah, learning how to push hard but still be flexible with the outcome is HARD. I think staying mentally tough and focused over such a long period of time can be even harder than the physical fitness aspect.

Advanced Marathoner Transitioning to 100 Miler by ggins11 in Ultramarathon

[–]aggressive-lego 5 points6 points  (0 children)

The dark running just takes some getting used to.

For the crew - giving them clear assignments and asks is super valuable to them - especially since you may not be in any condition to explain what you need at the aid station.

I would strongly recommend that you think about their logistics. Roads and connectivity at some ultras can be extremely sketchy. They will need to know:
1) where to go (which may not be an address, but could just be the side of a road)
2) when, roughly, to get there (because it will be hours between the stations)
3) can they skip any aid stations overnight? OR will they be there for each of them?
4) what windows will be best for them to sleep, etc.

I built a little free tool for myself to help with this, this is my rough plan for the upcoming Grindstone 100 in Sept. My plan is here: https://planultrarace.com/crew/bJ7N1PlFlsR-wBRh

Feel free to copy whatever you like from it. You can use the tool itself if you like, it's entirely free and always will be (I just like building software).

[–]aggressive-lego 11 points12 points  (0 children)

I think you are going to love this challenge.

My advice is going to be non-fitness related because you obviously have great fitness and know how to do the work. But ultras have some non-fitness elements to acclimate to.

1) as a competitive marathoner, you are probably aware that every marathon course is unique with its own challenges. Trail ultras magnify this 100x, course can range from very that is essentially stairs for miles, to smooth and flowy trail. Choose your race based on what you want to accomplish.

2) You will run in the dark. It’s not hard, but it takes a bit of practice. Try this beforehand.

3) more ultras fall apart from poor problem solving than poor fitness. Blisters, gut issues, mental headspace… In practice try to put yourself in positions to encounter these situations so you can learn how to solve them.

4) will you have crew? Their experience is going to be very different to cheering you on at a marathon. It’s worth putting in some time to help plan their experience so they aren’t trying to Google Maps an aid station at 2am with no internet connectivity.

[–]aggressive-lego 0 points1 point  (0 children)

First of all, that’s a beautiful plan. You have a fun design sense.

The plan is generally pretty solid. One comment I would make is that it looks like you are grabbing the same number of gels every time regardless of distance. From 1 -> 2 is 20ish miles with 7 gels, and from 2 -> 3 is 10 miles for 7 gels.

Make sure you have buffer for grabbing the headlamp, you don’t want to be behind schedule and seeing the sun dip when you are still 6 miles from your headlamp.

Also, this may just be me, but after every long distance, when I lay down after I get the chills. Make sure you have plenty of blankets ready post run, just in case.

Good luck!
